The only thing that matters is what he posts.
Don't be so ridiculous, Ryszard. This is PF. Everything matters and people are treated in a horrible way all the time. If they survive it, they become PFers - a part of the family no matter what.

Apart from being paranoid we are also very nosy and prying, so don't be surprised if we eventually find out who you are in the real life. Happens all the time here. I know who some posters are because they told me, but about one of them I was so curious that I had to find out myself without his knowledge. I am a discreet person though, so don't worry. ;)
